WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 369,299, dated August 30, 1887.

Application filed February i3, 1887. Serial No. 226,430. (No model.)

To @ZZ whom, t may concern.:

Be it known that I, NATHAN RUEENs'rEiN, of Chicago, county of Cook, and State of Illinois, have invented certain Improvements in XVash-Boilers, of which thefollowing isaspeciiication.

My said improvement will be fully described hereinafter with reference to the accompanying drawings, in which- Figure 1 represents a perspective view of my device in a boiler ot' common form, the sides being broken away to display the construction of my device in connection with the boiler; Fig. 2, a longitudinal central vertical section of the boiler and my device; and Fig. 3, a horizontal section ol one end of my device, taken as indicated by the broken line :c

- a in Fig. 2; Fig. 4i, a bottom view of an end of the same, and Fig. 5 a detailed View of parts.

A indicates the boiler, and B my device, which consists of a floor or second bottom to the boiler; and it is provided at each end with a hollow standard, C, which is composed of two rectangular tubes, E, and a depression of like form between the two tubes E, the result of which combination is that when the two tubes, as well as the floor, are soldered or otherwise fastened to the inner ends and sides of the boiler, as they must be, a large reotangular tubo, G, will be formed between the other A two and the ond of the boiler, and it should be of about the same capacity of both the smaller tubes added together. The boiler and my said attachment may be made of tin or other suitable sheet metal or other metal.

When the boiler is placed upon any heater, the water on the bottom becomes heated and turned partially into vapor and seeks to escape, and the only channels of escape are the tubes Gr, and so the hot water and steam rush up through them and are discharged through pipes I, and these pipes are so inclined that the streams of water and steam will strike the clothing to be cleansed near each side ofthe wall of the boiler and agitato them and force them around and around the boiler. The pipes I are inclined in opposite directions, as shown in the drawings, so that the streams at each end cooperate in this important work of agitating the clothes and freeing them from dirt.

In order to avoid friction as much as possible in the passage of the hot water and vapor up from the bottom of the boiler, the semi-tir bular ways or guides D, of like material with the false bottom B, are placed and fastened in the angles made by the standards with the iioor of B, so that the passage will be a covered one. Then, in order that the water and condensed vapor, after their action upon the clothing, and then having been somewhat cooled, may nd their way back again to the bottom of the boiler, to be again heated and vaporized, the tubes E are perforated with holes Ffrom top to bottom on their sides next to the Walls of the boiler. The having these holes in their outer sides is an important feature in the operation of the device, because then the holes are nearly, if not quite, out of the reach of the clothes, and consequently the clothes cannot come directly against them and stop them up, as they would do if the holes were in the sides which face to the short center of the boiler. The lower ends, H, of these tubes are curved in such a manner as to dis charge the water on a level with the bottom of the boiler and touching the same, and their lower ends are each inclined outwardly next to the walls of the boiler, in order that the streams from them may not meet or interfere with the hot water in its passage from the bottom upward through the chambers D G.

In order that the tubes I may not be obstructed by anything that might enter them from the boiler, they are provided with perforated diaphragms i, as shown in Fig. 2.

It is believed that my device has been so fully hereinbefore described that its operation will be apparent. AThe water in the bottom of the boiler is forced by the agency of heat up through the channels D and tubes G, and discharges through pipes I upon the clothing, and effects such an agitation upon them as will render any other friction or rubbing unnecessary to eiiect the cleaning of them. Instead, however, oi' fastening my attachment, consisting of the floor B, having its downwardly-projecting flange and water-channels, rigidly to the sides and ends of the boiler A, it may be side of seid tube G, all Substantially as shown attached thereto'in such a. manner as to be removable When required.

VhatI claim as my invention, und desire t0 secure by Letters Patent, is

The combination of the boiler provided With the flanged false bottom B,provided at each end with an upwardly-inclined guide, D, and the hollow standards C, Connected with said guides,

each standard consisting of an imperforate eentml tube, G, provided with u discharge-noz# zle, I, and with perforated tubes E on each and described, whereby the Water and steam beneath the false bottom are discharged through the imperforate pipes G and the Wa,- ter returned beneath the false bottom through perforated pipes E, as and for the purpose set forth.`
